This dashboard presents information on COVID-19. The {coronavirus} dataset package is available on CRAN and comes from the [John Hopkins University Center for Systems Science and Engineering](https://hub.jhu.edu/2020/01/23/coronavirus-outbreak-mapping-tool-649-em1-art1-dtd-health/). The {coronavirus} dataset is updated daily by @Rami_Krispin (https://ramikrispin.github.io/coronavirus/)).
I take this opportunity to thank Rami Krispin for sharing his work and code with the #rstat community. His dashboard on coronavirus has helped me tremendously to improve my knowledge of the {flexdashboard} package.
